无线充电式移动电源及充放电方法Wireless charging mobile power supply and charging and discharging method

技术领域technical field

本发明涉及一种无线充电电源，尤其涉及一种可通过无线方式充放电的移动电源及充放电方法。The invention relates to a wireless charging power supply, in particular to a mobile power supply capable of charging and discharging in a wireless manner and a charging and discharging method.

背景技术Background technique

随着人们生活水平的提高，电子产品（例如手机、手电筒、小风扇、电动刮胡刀、桌灯、头灯、露营灯等产品）已经成为现代人必不可少的常用品，这些产品有时由于使用的频繁和使用场所的局限性，需要经常充电，为了便于外出充电，现有技术人员研发出了一种移动式充电电源，这种移动式充电电源内包含有蓄电电池，在使用时可通过以下几种方式充电：一种是直接通过数据线将电子产品和移动式充电电源的充电插头连接起来，能量从充电插头导入电子产品的电池中储存起来；第二种将移动式充电电源设置成充电座的方式，通过充电座将能量导入电子产品的充电电池内储存起来。由于第一种需要使用数据线才能完成充电，每次充电都需要将数据线的一端插到电子产品上，等到充完电后再拔下来，这样不仅麻烦，而且常常出现短线、插座松脱等问题，不但充电效果不稳定，而且会对电子产品造成损害；第二种必须将电子产品放入充电座内，必须确保电子产品的充电端与充电座的放电端连接在一起，在晃动或者长时间使用后往往会由于错位造成电子产品的充电端和充电座的放电端接触不良，以使电子产品与充电座连接不稳定。另一方面，上述移动式充电电源对于应急灯、露营灯等产品而言，由于这类电子用品在不使用时往往处于充电状态，使用时，使用者有时难以及时将产品从充电座或者充电电源上取下，为此，现有技术人员开发出来了一种非接触式充电电源。With the improvement of people's living standards, electronic products (such as mobile phones, flashlights, small fans, electric shavers, table lamps, headlamps, camping lamps, etc.) The frequency of use and the limitations of the place of use require frequent charging. In order to facilitate charging when going out, existing technical personnel have developed a mobile charging power supply. This mobile charging power supply contains a storage battery, which can Charge in the following ways: one is to directly connect the electronic product with the charging plug of the mobile charging power supply through the data cable, and the energy is stored in the battery of the electronic product from the charging plug; the second is to set the mobile charging power supply In the way of forming a charging stand, the energy is introduced into the rechargeable battery of the electronic product through the charging stand and stored. Since the first type requires the use of a data cable to complete charging, one end of the data cable needs to be plugged into the electronic product every time it is charged, and then unplugged after charging is complete. This is not only troublesome, but also often leads to short wires and loose sockets The problem is that not only the charging effect is unstable, but also it will cause damage to the electronic product; the second type must put the electronic product in the charging stand, and must ensure that the charging end of the electronic product is connected to the discharging end of the charging stand. After a long time of use, the charging end of the electronic product and the discharge end of the charging stand will often be in poor contact due to misalignment, so that the connection between the electronic product and the charging stand is unstable. On the other hand, for the above-mentioned mobile charging power supply for products such as emergency lights and camping lights, since such electronic appliances are often in a charging state when not in use, it is sometimes difficult for users to remove the product from the charging stand or charging power supply in time when in use. For this reason, prior art personnel have developed a kind of non-contact charging power source.

这一类非接触式充电电源可通过线圈单元的电磁感应对负载通过无线感应的方式充电，但是这类非接触式充电电源内电池充电时，必须通过数据线进行充电，充电效果不稳定，而且会对电子产品造成损害，因此，急需一种可解决上述问题的非接触式充电电源。This type of non-contact charging power supply can charge the load by wireless induction through the electromagnetic induction of the coil unit, but when charging the battery in this type of non-contact charging power supply, it must be charged through the data line, the charging effect is unstable, and Can cause damage to electronic products, therefore, a kind of non-contact charging power source that can solve the above-mentioned problems is urgently needed.
